Please help! I am trying to use my comcast remote with my marantz es7001 receiver. Comcast remote is silver with red ok button. I've read many of the forums. I've used the setup codes 30189 & 21781. I've used all the piggyback codes. I am sure that I am following all steps correctly. The 30189 & 21781 codes do go through the red light does blink twice on my remote. Then when I do the 994 piggybacking still nothing happens. I am extremely frustrated and really just want to have my comcast control the volume of the marantz so I don't have to use 2 remotes. Please help!

Vicky, thanks for the response. I did read that before and went through all steps and examples. None of it worked. The 30189 & 21781 codes seem to take (lights blink twice). But buttons still do not work. I'm very frustrated because I am doing all steps correctly but it is not working. Any thoughts?

The Volume and Power buttons lined up with the Marantz Reciever only the device number was changed so thats how I came up with Vol Down and Mute.

I don't know where Dave found the OBC to try for the power toggle. I only found the Discrete PowerOn code that used an RC5x signal. As far as I know there is no way to send an RC5X device 11 code without a cable.

My internet connection is S L Oooo Wwwwww . . . so I wasn't able to do more searching at RemoteCentral to see if there is more than the volume and power on._________________Remember to provide feedback to let us know how the problem was solved and share your upgrades.
